Description

Technical Field

[0001] The utility model relates to the technical field of positioning tooling, in particular to a steering knuckle mounting seat processing positioning device. Background Art

[0002] The bogie is the most important component system in urban rail transit vehicles, and the knuckle mounting seat is an important component in the bogie braking system. The strength and rigidity of the knuckle mounting seat are related to the safety, reliability and comfort of operation. Its quality directly affects the operating performance of the entire car body and bogie, as well as the normal operation and safety of subway vehicles.

[0003] Because the steering knuckle mounting seat has high quality requirements and is difficult to process, it has a direct impact on product quality. The traditional rail passenger car steering knuckle mounting seat processing method is very complicated, difficult to operate, scattered processes, and the repeated positioning accuracy cannot be well guaranteed. In addition, it is impossible to use a better method for clamping, and the use of processing equipment is also limited. First, the steering knuckle mounting seat is marked with processing lines, alignment lines, reference lines, and contour lines on the marking platform. During processing, an ordinary center is installed at the bottom of the workpiece for height adjustment. Next, a height gauge is used to manually adjust and align the drawn alignment line with a height gauge. The operation is difficult, time-consuming, and requires repeated adjustments. This operation is cumbersome, complex, and difficult to operate, and requires very high operating skills of the workers.

[0004] However, clamping the workpiece with an ordinary pressure plate cannot meet the quality requirements of the steering knuckle mounting seat, which will result in poor processing quality, inconsistent dimensions, low processing accuracy, low efficiency, long auxiliary time, and cumbersome and complicated operations, which will seriously affect the product performance and safety.

[0005] Therefore, how to provide a hydraulic device for machining and positioning a railway passenger car steering knuckle mounting seat with high positioning accuracy is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0006] The utility model provides a steering knuckle mounting seat processing and positioning device, which solves the technical problems of low processing precision, low efficiency, long auxiliary time, cumbersome and complicated operation of traditional steering knuckle mounting seat clamping tooling.

[0007] The utility model solves the above-mentioned technical problem with the following technical solution: a steering knuckle mounting seat processing and positioning device, the steering knuckle mounting seat having a first end and a second end arranged oppositely and having a positioning surface and a processing surface arranged oppositely, the end surface of the first end is provided with a positioning groove penetrating the positioning surface and the groove bottom of the positioning groove is a positioning side surface, and the end surface of the second end is provided with a clamping groove penetrating the positioning surface and the processing surface; comprising: a fixing plate, a side plate, a first positioning block, a second positioning block, a side positioning assembly, an end plate and an end clamping assembly,

[0008] The top surface of the fixed plate has a first side edge and a second side edge arranged opposite to each other and has a first end edge and a second end edge arranged opposite to each other, and the first end edge and the second end edge are both vertically adjacent to the first side edge and the second side edge; the bottom surface of the side plate is vertically fixed to the first side edge of the fixed plate; the first positioning block, the second positioning block and the side positioning assembly are fixed at intervals on the plate surface of the side plate corresponding to the second side edge, the first positioning block is opposite to the positioning surface to position the positioning surface, the second positioning block is opposite to the positioning side surface to position the positioning side surface, and the two positioning ends of the side positioning assembly are respectively in contact with the two inner groove walls opposite to the clamping groove; the bottom surface of the end plate is vertically fixed to the first end edge of the fixed plate; the end clamping assembly is fixed to the plate surface of the end plate corresponding to the second end edge and its two clamping ends are respectively clamped on both sides of the first end.

[0009] The beneficial effects of the utility model are as follows: the structure of the traditional steering knuckle mounting seat pressure plate clamping tooling is changed, and the steering knuckle mounting seat is first accurately positioned by utilizing the first positioning block and the second positioning block to contact the positioning surface and the positioning side surface respectively; and then the two positioning ends of the side positioning component are contacted with the two inner groove walls opposite to the clamping groove, and the two clamping ends of the end clamping component are respectively clamped on the two outer sides of the first end, so that the steering knuckle mounting seat can be quickly clamped, and the positioning and clamping of the steering knuckle mounting seat can be completed quickly and accurately, thereby reducing the positioning and clamping time and improving the subsequent machining efficiency.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the side positioning assembly and the end clamping assembly have the same structure and both include: a fixed plate, a clamping cylinder, a truncated cone body and two clamping claws.

[0012] The fixing plate is fixed parallel to the plate surface of the side plate corresponding to the second side edge or the plate surface of the end plate corresponding to the second end edge, and the middle part of the fixing plate is provided with a sliding hole extending along its axis and two guide holes are provided on its opposite outer circumference, and the two guide holes are both vertically connected to the sliding hole; the clamping cylinder is fixed to the side plate or the end plate and its piston rod passes through the corresponding side plate or the end plate; the frustum body is slidably connected in the sliding hole and its large diameter end is fixed on the piston rod of the clamping cylinder passing through the side plate or the end plate; the two clamping jaws are the two positioning ends of the side positioning assembly or the two clamping ends of the end clamping assembly, and the two clamping jaws are respectively slidably connected in the two guide holes and their ends close to each other are respectively slidably connected to the opposite outer circumference of the frustum body through connecting pieces, so as to approach or move away from each other as the frustum body slides, and the ends of the two clamping jaws far away from each other both extend out of the corresponding guide holes to clamp on the two inner groove walls opposite to the clamping groove or on the two outer sides of the first end.

[0013] A further beneficial effect of the above-mentioned use is that the piston rod of the clamping cylinder is used to push the conical body to move back and forth in the sliding hole. Since the ends of the two clamping jaws that are close to each other are slidably connected to the opposite outer circumferential surfaces of the conical body through connecting pieces, the clamping jaws can be pushed closer to or away from each other while the piston rod reciprocates, thereby achieving the clamping and release of the steering knuckle mounting seat.

[0014] Furthermore, the connecting piece is a long strip, and the ends of the two clamps close to each other are provided with connecting sliding holes running through both sides thereof, and the cross-section of the connecting sliding holes is a trapezoidal structure; the two long strips are respectively fixed on the opposite outer circumferential surfaces of the truncated cone body and their cross-sections are both trapezoidal structures, and the two long strips are respectively slidably connected to the two connecting sliding holes.

[0015] The further beneficial effect of adopting the above is: by using the long strip of trapezoidal structure to be slidably connected in the connecting sliding hole of the trapezoidal structure, the clamping jaw can be prevented from detaching from the truncated cone body without hindering the clamping jaw from sliding along the side of the truncated cone body, thereby improving the stability of the clamping jaw's sliding and clamping.

[0016] Furthermore, it includes multiple oil pressure components, each of which includes: a pressing cylinder, a connecting strip and a pressing plate, the pressing cylinder is located on one side of the first positioning block, the second positioning block and the side positioning assembly and is fixed in front of the side plate; one end of the connecting strip is hinged to the pressing cylinder; one end of the pressing plate is hinged to the piston rod of the pressing cylinder and the middle part is hinged to the other end of the connecting strip, and the other end can be pressed on the processing surface.

[0017] Furthermore, it also includes a floating positioning block, the positioning surface is divided into a plane section and an inclined surface section in sequence from the second end to the first end, and the first positioning block is in contact with the plane section; the floating positioning block is located between the second positioning block and the side positioning assembly and is rotatably connected to the front of the side plate through a rotating shaft and a rotating shaft seat, and the floating positioning block can be in contact with the inclined surface section.

[0018] A further beneficial effect of the above method is that, since the accuracy of the inclined surface segment is relatively low, the adaptability of the positioning device can be improved by utilizing a floating positioning block that is rotatably connected to the front of the rear plate.

[0019] Furthermore, it also includes a plurality of positioning heads, which are respectively fixed on the first positioning block, the second positioning block and the floating positioning block and are respectively in contact with the plane segment, the positioning side surface and the inclined surface segment.

[0020] Furthermore, it also includes a plurality of bottom support oil cylinders, which are fixed on the fixing plate at intervals and whose piston rods can all contact the bottom side surface of the steering knuckle mounting seat.

[0021] A further beneficial effect of the above method is that the stability of the positioning and clamping of the steering knuckle mounting seat can be improved by utilizing the piston rods of multiple bottom supporting cylinders to contact the bottom side surface of the steering knuckle mounting seat.
